|
|
Answer:
|
|
def main(char: str) -> None:
|
|
if char.isupper():
|
|
print(f"{char} is an uppercase letter.")
|
|
elif char.islower():
|
|
print(f"{char} is a lowercase letter.")
|
|
else:
|
|
raise ValueError("Invalid input. Please enter an alphabetic character.")
|
|
|
|
if __name__ == '__main__':
|
|
main('A')
|
|
main('a')
|
|
main('B')
|
|
main('b')
|
|
main('1') # also works with a int
|
|
|
|
Output:
|
